CSSD Body Composition 4

Question 1

Air displacement plethysmography (Bod Pod) measures body composition by assessing:

Accepted Answer

Body volume through air displacement in a sealed chamber

Answer

The Bod Pod calculates body volume from the amount of air displaced when a subject sits inside a sealed chamber, then derives body density and fat percentage using the Siri or Brozek equation.

Question 2

Which statement about visceral adipose tissue (VAT) and athletic performance is most accurate?

Accepted Answer

Higher VAT is associated with greater insulin resistance and metabolic disease risk, even in athletes

Answer

Elevated visceral adipose tissue increases inflammatory cytokines and insulin resistance regardless of fitness level, posing metabolic health risks even in physically active individuals.

Question 3

A distance runner's body fat drops from 12% to 8% of body weight over a competitive season without a planned weight loss goal. The CSSD's primary concern should be:

Accepted Answer

Low energy availability and potential Relative Energy Deficiency in Sport (RED-S)

Answer

Unintentional body fat loss in an endurance athlete suggests low energy availability, a hallmark of RED-S (formerly the Female Athlete Triad), with risks to bone health, hormonal function, and performance.

Question 4

What is the primary limitation of using BMI to assess body composition in collegiate football linemen?

Accepted Answer

BMI cannot differentiate between fat mass and fat-free mass, classifying muscular athletes as 'obese'

Answer

BMI is weight divided by height squared and cannot distinguish muscle from fat; highly muscular athletes frequently fall in the 'obese' BMI category despite having low body fat percentages.

Question 5

When counseling a female gymnast about body composition, which approach aligns with current CSSD ethical and clinical standards?

Accepted Answer

Focus on performance outcomes, functional strength, and adequate energy intake rather than weight targets

Answer

Current standards emphasize performance-based and health-centered goals over appearance or weight targets, particularly in aesthetically judged sports with elevated disordered eating risk.
